My 22 year old TT has a anode rod screwed into the back of the water heater. In a very hard to reach position.
Unlike the newer water heaters that I've seen where the rod is part of the drain plug on the bottom of the water heater this one is mounted on the back and high up on the tank. I've had the TT for about 4 years and I've never changed it. I have no idea if it ever has been changed. I'm afraid to strip out the threads removing it.
Is it worth the risk ? Or, should I just leave it alone until the water heater leaks and then replace it. Which I would have to do anyway if I strip out the threads now trying to replace it.
